According to the American Water Works Association, 10 gallons of water per person per day is lost in the average system through leaks or breaks in underground pipes, valves and hydrants. In many cases this tremendous volume of water is being treated and pumped. When it leaks out you lose more than water, you lose money! How can you afford to let these leaks continue?

Call your local sales office to set up a few days of leak locating now! The savings from eliminating lost water will more than pay for the service.

  • Do you know the depth of the line?
  • Do you know the pressure of the line?

About the JD7Investigator™

The Investigator is a pressurized pipe inspection and leak detection system for 100m investigations within distribution water mains. The systems camera and hydrophone technology is matched for 75mm to 300mm diameter pipe work for complete asset condition examination and leak finding. Unlike any other commercially available technology, the Investigator can be launched through fire hydrants, pressure fittings, air valves, gate valves and quadrina tapings at full mains pressure. The Investigator is capable of 100m travel with and against the water flow in water mains up to 16bar pressure.


The system is extremely robust, allowing reliable results to be achieved within harsh environments. All light levels are focussed to precisely match the field of view of the camera module, offering significantly enhanced images.

Accurate Measurements

The system uses an electronic or manual drive mechanism to feed and retract the sensor head within the water main. This ensures a consistent feed rate and increases control of the position of the sensor. The mechanism also allows water integrity within pressurized water mains.

Audio and Visual Sensors

The integral hydrophone and sonde is operated in parallel with the camera system, offering visual and acoustic data all as well as locating the area of interest from one operation. The sensitivity on the hydrophone technology is incredible, where many filtering and frequency options are offered with the technology.
